A motion platform comprises a base, a top, a pair of positioning motor assemblies mounted to the base, and an arm assembly extending between each of the positioning motor assemblies and the top of the platform. Each of the arm assemblies is responsive to rotary motion of a respective one of the positioning motor assemblies and includes a rotating arm mounted at one end on the motor shaft and rotatable over a full 360-degree arc. Sensors detect the position of the arm assemblies and the speed and amount of rotation of the positioning motor assemblies. The motion platform further comprises a microcontroller, electrically connected to the positioning motor assemblies and responsive to input commands and to signals from the sensors, for controlling rotational speed, rotational direction and rotational extent of the positioning motor assemblies and thus angular displacement of the top of the motion platform relative the base. The motion platform has two degrees of freedom, pitch and roll, to mimic real world motion.

1. A motion platform comprising:a base; a top; a support member for supporting the top relative to the base with freedom of movement about at least one horizontal axis; a pair of positioning motor assemblies mounted to said base; an arm assembly extending between each of said positioning motor assemblies and said top, said arm assembly being responsive to rotary motion of a respective one of said positioning motor assemblies and adapted to rotate 360 degrees about said respective positioning motor assembly to effect relative movement of said top about said at least one axis; and a microcontroller electrically connected to said positioning motor assemblies for controlling a rotational speed and a rotational direction of said positioning motor assemblies and thus angular displacement of said top of said motion platform.
